Chunity (ChucK for Unity): Release!
by Jack Atherton 29 Jul '22

29 Jul '22

Dear all, Hello! I'm happy to announce the initial official release of Chunity (ChucK for Unity)! http://chuck.stanford.edu/chunity/ http://u3d.as/1bvM Chunity is the integration of ChucK in Unity. (For those of you not familiar with the Unity game engine, Chunity gives you the ability to do realtime sound + music generation natively in Unity, tightly coupled to interactions with graphical objects.) You can use most (possibly all?) ChucK features, run new ChucK code on-the-fly at any time, and communicate between Unity and ChucK using "global" (new keyword!) ints, floats, strings, Events, and 1D int and float arrays. (More types to come!) You can even run multiple VMs that share the same strong timing! Check out this video of things people have already made with Chunity: https://vimeo.com/263613454 And check out the original description of Chunity in this NIME paper: http://chuck.stanford.edu/chunity/files/2018-nime-chunity.pdf We want to know what you all do with this! Please feel free to send works in progress, bug reports, feature requests, finished works, etc. to the chuck-users mailing list! We are also planning to send a sparse series of follow-up emails covering tutorials, new features, and cool projects that people in the community have created. Please see the tutorials, documentation, etc. at the official Chunity website: http://chuck.stanford.edu/chunity/ Thank you and happy ChucKing!! Best, Jack + the ChucK team Music:Computing:Design @ CCRMA

Does a Std.system call block concurrency?
by federico lopez 01 Jan '21

Hi, Is the ChucK thread disrupted by the execution time of a Std.system script call? In the code below, sporking a fast script, e.g. Std.system("sleep 0"), there is no noticeable disruption, but sporking a time consuming version e.g. Std.system("sleep 3") there is a disruption in the other sporks. I'm trying to call R scripts using ChucK concurrency. // test code, run with --caution-to-the-wind command-line flag Noise n => Envelope e => dac; fun void metro() { while(true) { e.keyOn(); 10::ms => now; e.keyOff(); 990::ms => now; <<< now, "samples" >>>; } } fun void callSystem() { while(true) { Std.system("sleep 0"); // comment this to test //Std.system("sleep 3"); // uncomment this to test 1000::ms => now; } } spork~ metro(); spork~ callSystem(); while(true){10::ms => now;} // end test code

Fifo with Chuck?
by Forrest Curo 28 Dec '20

28 Dec '20

This is a built-in feature in csound on linux, that you can send score lines to a fifo that csound -L will pick up and execute. With chuck, I can open a fifo as a file, read it, send it a line of numbers -- but as soon as chuck has read the last number, it reads the eof and stops working. Is there a way to halt just short of the eof? I suppose I could add a dummy value at the end... but is there something less clumsy available?

64-bit Chugins on Windows?
by David Braun 01 Dec '20

01 Dec '20

I'm seeking help getting Chuck 1.4.0.1 to recognize a chugin that I've compiled with CMake. I've compiled chuck.exe from source and confirmed that it's 64-bit with chuck --version. I've also compiled the chugin as 64-bit. When I do all those steps as 32-bit, the chugin works. However, for 64-bit, chuck can't load the chugin. I've tested with miniaudicle and from command line. I'm using CMake on Windows to make the chugin. Hopefully a missing compile flag etc isn't causing the issue. More details are here: https://github.com/ccrma/chugins/issues/45 Thank you!
